Safari & Youtube problem

I have a iBook G4 running on Mac OS X 10.3.9 with a 1.07 GHz PowerPC G4 processor with 256 MB memory.

Each time I try accessing the Youtube website via Safari (1.3.2) the browser crashes. I know this is a common problem as I've googled it and there are lots of people having the same problem but there doesn't seem to be any answers.

Also everytime i try and download something, it downloads the whole file then says mounting failed. This happens with anything from firefox, adobe, itunes.

Hmmm... Well do you have your flash player up to date? That could cause the safari problem with youtube. Also make sure you have Java enabled. Have you tried Firefox with youtube? As for the mounting issue, sounds like an issue with the OS rather than the browser. Where do you have downloads set to default as? Go into preferences and make sure it says (Save Files to: Desktop)
